Superposition of lung metastases of prostate adenocarcinoma on heart as a cardiac metastases: A case report

Journal of Oncological Sciences, 2016
Background: Primary or secondary malignancies of the heart is rare and difficult to diagnosis. Most cardiac masses are detected incidentally. Positron emission tomography-computed tomography, thorax computed tomography are valuable tools for staging the ...

Multi-epoch Doppler tomography and polarimetry of QQ Vul [PDF]

, 1999
We present multi-epoch high-resolution spectroscopy and photoelectric polarimetry of the long-period polar (AM Herculis star) QQ Vul. The blue emission lines show several distinct components, the sharpest of which can unequivocally be assigned to the ...

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

Fluorodeoxyglucose-positron emission tomography/computed tomography imaging features of colloid adenocarcinoma of the lung: a case report

Journal of Medical Case Reports, 2017
Background Colloid adenocarcinoma of the lung is a rare subtype of variants of invasive adenocarcinomas. We report the appearance of this unusual entity on 18F-fluorodeoxyglucose positron emission tomography/computed tomography.

Influence of X-ray computed tomography (CT) exposure and reconstruction parameters on positron emission tomography (PET) quantitation

EJNMMI Physics, 2020
Background The CT of PET CT provides diagnostic information, anatomic localisation and attenuation correction (AC). When only AC is required, very lose dose CT is desirable.
